    my macbook pro 15inch running on maverick when i try to click on wi-fi says no hardware installed please help i need wifi and and under network staus wi-fi is fail and under network airport is not connected can anybody help the wifi icon has a x and does not even let me turn it on

    Have you attempted to reset the SMC? That would be the first step. Hold the left control, option, shift key and the power button for about 5 seconds and release. Then try to reboot. Might as well reset the PRAM as well. Hold command, option, P, R on start up until the machine restarts. If that doesnt' have any affect we'll have to dig deeper into a potential hardware failure.
    If this method doesn't work, check the webcam that will tell the problem is on the iSight & WiFi cable. If your webcam is ok, then it'll be the WiFi card problem. Hope it can help ;-)

  • Macbook air adapter heats up really bad ! please help

    Hello Folks !!
    This is Jan and i purchased macbook air 11 inch 64 gb ultrathin laptop 2 months back. i use this laptop for watching youtube videos or occasional skype chat with family and friends and each day i dont use my laptop for more than 4 hours.
    Yesterday i was watching youtube video and after 2 hrs, the adaptor got so hot and i was afraid and pulled power and switched off laptop.
    Are thare any macbook air adaptor knows issues and why my macbook air adaptor heats up really bad ?
    Please help me resolve my issue with macbook air adaptor.
    Please help.
    Thanks
    Jan

    The power adaptor will always get a little warm or even hot during use.
    How hot did it get? Was it smoking, melting, or discoloring?
    If not, then that little bit of heat is usual and you shouldn't worry about it too much.
    Hope this helps,

  • How do I download my Microsoft office on to my MacBook Air using airdrop from my iMac? Please help

    How do I download my Microsoft office on to my MacBook Air using airdrop from my iMac? Please help

    Out of curiosity, does Microsoft's licensing allow for such an install and/or more than one install? I just did a cursory check on their licensing and found that most are only licensed for one computer unless you buy a special key card.
    I had a different app once that was only allowed on one computer; it would not install on the other Mac. You may therefore encounter problems - since you must have an install CD, why not use that if you have the key card allowing you to install it on more than one?

  • Macbook Air 11" Log-In Language Unchangeable. Please Help!

    Hello All
    I recently purchased this MacBook Air 11" from someone, and it had some folders in Asian (yes, I know Asian is not a language per se, but I do not want to say Simplified Chinese, or Japanese, or Korean, or whatever for fear of offending people that speak the language). I went to System Preferences and changed the language in region/language to English. The MacBook when purchased didn't have a password to login.
    Later on my nephew recommended I format the system, so it was anew. He started to try formatting it, only realising that the language was still somehow Asian. He knew how to go by the prompts thankfully, and ended up formatting it with one wipe. It was still Asian fonts staring at us by the end of the process though.
    He changed some of the settings and ended up getting it to show in English. He added a login/pw combo this time, and whenever we are faced with the login screen (you see below in the pic I took with my mobile) now, it is in Asian. Everything else seems to be in English, just that screen.
    This worries me, as when I may need to format the system once more, what if the process pops up in Asian again, and I have no access to my nephew, I would be stranded!
    Somehow, we came to the conclusion that this particular MacBook was set to have Asian as the default language. Am I wrong?
    Login Screen (by the way, how does one take a screenshot of the login screen on a MacBook Air?)
    I went through a few threads and none helped me. I took a screenshot of the Systems Preferences, in case someone tries telling me to go to the Language/Regional settings to change the language, as I do not have access to it through there.
    System Preferences
    Thank you for your time and concern.
    isa

    From the menu bar, select
     ▹ System Preferences... ▹ Language & Text ▹ Language ▹ Edit List...
    Deselect each unwanted language and click OK. Then select the Region tab, and select your region from theRegion menu at the top.
    Close the preference pane. You may have to log out and log back in for the change to take effect.

  • Macbook Air Trackpad And Keyboard Unresponsive!! PLEASE HELP!

    Hello everyone, a while ago (about 2 months) my Macbook air started having troubles with its trackpack and keyboard. At random times they would become unresponsive and just stop working. They would work for like 1 second when the computer turns on but then it would stop. A couple weeks ago the problem stopped occuring the keyboard and trackpad were working fine and dandy. Of course until last night, I open the computer and the trackpad and keyboard won't work.. The keyboard lights are on and the power button works but nothing else does it is extremely frustrating! I did an SMC reset which worked for like 5 minutes until it stopped working again. I have done a NVRAM reset nothing, I have done everything that I have seen but I need a fix for this! The mac is running OS X 10.9.3 and I am pretty sure that is the latest. Please help me guys I am really getting frustrated with this undying problem ;/

    you don't need to disassemble your device.
    4 days is a lot.
    maybe rust has already been created.

  • MacBook Air "Stuck" on booting OS X ? Please help {: - )

    Ah, this is my only computer, and I need to finish a college assignent, and don't ahve any cash to take it to a Mac Store; Would appreciate any and all input!
    Okay, my MacBook Air "was working fine last night" as the line goes, when I went to boot it this morning, the dispaly would come on, i could see the "APPLE" logo, and the "status circle" thing circling.
    the display will stay on for about 63 seconds or so, then contines to cycle. I have checked the magsafe adaptor, it is getting power.
    the led sleep indicator is not doing a funky blink pattern, nor does it make any "new" sounds.
    I have scoured the Mac website under the TROUBLESHOOTING section, but to no avail. there doesn't seem to be POWER ON issue, and i don't think, based off of what I read, that it was a battery issues, but what appears to be happening is the OS is not loading.
    Is there another way to try to REPAIR to OS? Not sure what the issue is, but, i am really confused by this! I have had the computer PROBLEM FREE for aver a year now, and i am at a loss, and have to turn in a major paper for college on Tues!
    THANKS!

  • My iPad Air 16GB says I have 12GB? Please help :(

    My iPad air 16GB arrived today and when I check my stats I see I have 12GB. Why does it say that? I should have 16GB and not 12GB. I went on settings and about. Really appreciate the help
    Thank you.

    The iOS and built-in apps take up space.  12GB free space is normal for a new 16GB iPad.  It's been like this for all computers, tablets, smartphones, etc for as long as they've been made.

  • Locked out of macbook air after updating to mountain lion? please help

    Things like this always happen to me :(
    I can remember locking it at work when my mate was playing on it so I locked it as I didn't want him on it and he knows my login pin. However it's been fine ever since this was done 5/6 months ago.
    I need it for work in the morning :(
    If I call apple with my serial number do you think they can help?

  • Can my mid 2011 macbook air be upgraded to wifi 802.11ac?

    Can my mid 2011 macbook air be upgraded to wifi 802.11ac? I am considering replacing my 802.11n router with the 802.11ac time capsule. Will this effect my download speed on my 802.11n macbook air (mid 2011)? can it be upgraded?

    No, you cannot change the Wi-Fi hardware in your Mac. The Time Capsule is still worth it due to its ability to make backups of your Mac via Time Machine.

  • When I plug in my iphone to my macbook air it says the computer is not granted to take the iphone information

    Hi
    When I plug in my iphone to my macbook air it says the computer is not granted to take the iphone information. So I haven t been able to import the iphone information (like photos) to my laptop.
    This is the first time it happened to me, because last week I could done that.
    Could anyone help me please fixing this issue?
    Thanks.

    Try unplugging any other USB devices. If you are using a hub, don't, connect the phone directly to a computer USB port.
    None of these are necessarily things you should do, but might help. For instance, if you plug the phone to an already busy hub, the phone might be "the straw that broke the camel's back" and lock out the hub.
